Deep plasmid annotation (pLannotate)

Annotate a plasmid against pLannotate's open-source feature library — a much larger signature set (GenoLIB parts + Swiss-Prot + FPbase + Rfam, cross-referenced against ~195k Addgene-deposited plasmids) than plasmid_annotate's built-in curated list, and it reports partial and low-identity hits as graded alignments rather than the pass/fail signature match plasmid_annotate does (that one is not exact-only either — signatures of 20 bp or more tolerate up to ~10% mismatches — but it reports a hit or nothing, with a mismatches count and an exact flag). Each feature here carries its percent identity, reference coverage and a fragment flag so you can judge a weak hit. Runs a multi-second search on a shared service and is therefore rate limited (see 429/503); use plasmid_annotate for an instant, unmetered first pass.
